I think that these are very high quality and look amazing. These are my go to when I'm working on paintless dent repair. My whole team loves them.

I really don't have any bad things to say about these.

I just installed it and so far it works well. Vernon Roofing

I'll just give an update after a week of use.

The HK 3490 has been a solid purchase after going through 2 other receivers that only lasted 4 years. The sound quality is crisp and the unit blends seamlessly with the rest of the audio visual components in the home theater. masonry columbia sc

None that I know of

I bought this because of the good review I've read and so far so good. I'll just give an update after a week of test. printingproslittlerock.com

I'll do the test first on the first week of use then I'll be back here for an update.

Nice looking and very good sound quality for a receiver. Affordable SEO Services

Can't think of any.

Great buy! So far it's good, recommendable for those who are looking for an affordable amp. sirspeedy

None so far, I'll just give an update if there is some.

The Harman Kardon HK 3490 is unusually good-looking for a stereo receiver (or any audio component, for that matter), with curved side panels and a gloss-black and dark gray front panel that give it a sleek, stylish look. The HK 3490's sound quality is excellent. fayetteville concrete

So far I dont see any but I would appreciate some help on integrating internet music.

The best receiver I ever brought! Greg │ Demon Eyes

Hard to locate proper selection button, difficult to read button labels.

Surprisingly good amp. Drives my T&A TMR 160 MKII TML boxes easily. That HK pumps up to 240W on 2ohms, 45ampere makes my TML's rumble. Very good stereo perspective, punchy, controlled basses. I suffered before with a Marantz PM7000, who was really stressed by my TML's (but soundstage was a bit better at tweets than this HK) , with State of the art digital input (Dolby modules if I'm not wrong) with tons of details. No noise, serious deep and full bass. For powerful music also for live jazz recordings more than sufficient up to upper hifi level. This hk is also fun to listen in lower levels. Virtual dolby is interesting feature. Very quiet and detailed mm input, though it can't compete with pricy mm/mc pre-amps. Rhis hk Never gets hot, even after hours of loud music (heat is no friend to semiconductors)¥. Impressive complete soundquality on FM with a wide stereo scenery.

Not the best amp to realize deepness in music. Some more spdifs or digital coax inputs more would have been nice.

This receiver is not beatable by its price. Period. Dont think less of him because it is not the flagship, which is HK990. The HK3490 is beautiful, heavy, and has tons of power. I use it with KEF IQ90 and it is a perfect match. I doubt you will have a better stereo for its money. My player is Marantz UD7007. The REAL power is not 2x120, but its 2x 140 which is enough to make my Kefs pump VERY strong. Definitive amp for life
